T all w hom t may concern Be it knownthat l, GEORGE HERREN, a

l citizen of the United States, residing at Great Bend, in the county ofBarton and State of Kansas, have invented new and useful Improvements inRadiator-Valves, of which the following is a specification.

This invention relates to radiator valves or valves especially designedfor use in connection with steam radiators, whereby the steam and waterof condensation are trapped in an effective and noiseless manner and thewater of condensation drained from the valve back into the radiator andto the return pipe of the heating system.

Another object of the invention is to provide novel means for adjustingthe seating of the controlling valve while at the same time admitting ofthe use of the silencer hereinafter particularly described.

`With the above and other objects in view,

the invention consists in the novel construction, combination andarrangement of parts, as herein described, illustrated and claimed.

In the accompanying drawings z-Figure 1 is a vertical diametricalsection through a radiator valve embodying the present invention. Fig. 2is a cross section through the same on the line 2-2 of Fig. 1, lookingupwardly.' Fig. 3 is a fragmentary vertical.

.Y section on the line 3-3 of Fig. 1. Fig. 1 is a detail perspectiveview of the cap remov, ing and seat adjusting tool to be used inconnection with the Valve.

Referring to the drawings 1 designates a radiator and 2 the vent pipethereof.

ln carrying out the present invention l provide a noiseless valve whichin the preferred embodiment thereof comprises a substantiallycylindrical main steam and condensation chamber 3 which yis supported bythe pipe 2, the latter communicating ,with the bottom of the chamber 3as clearly shown in Fig. 1.

4 designates a gravity drain pipe which extends from the chamber 3 backto the radiator, the pitch or inclination of said pipe being such as tocause the water to readily find its way into the radiator and fromthence through the return pipe of the system to the boiler.

The chamber 3 is provided with a removable cap 5 preferably threadedtherein y as shown and provided at diametrically opposite points withknobs or studs 6 adapted to be engaged by a combined screw driver andSpanner shown in Fig. fl, the main body of the Spanner being in the formof an annulus 7 formed with notches 8 to engage the studs or knobs 6 ofthe cap 5 thereby enabling said cap to be removed. Extending radiallyoutward from the annulus 7 is an arm 9 the end portion of which isformed into a screw driver point 10 for adjusting the valve seat as willhereinafter appear.

The cap 5 is formed with a central internally threaded opening 11 toreceive the threaded lower end of a valve chamber or cage 12 in whichworks a valve 13. The valve cage or chamber l2 is internally threaded inthe upper end thereof to receive a valve seat 14, the same being thread`i ed into the cage and formed with an internal cone shaped seating face15 at its lower end against which the correspondingly cone shaped face16 of the valve is adapted to rest under certain conditions.

The valve 13 is provided with a stem 17 extending downwardy within thechamber 3 and having fixedly attached thereto a valve controlling andextensible chamber or thermostatic element 18 which expands under thehead of the steam impinging thereon and serves thereby to force thevalve Stem 17 upwardly and close the valve 13 against its seat. A shortstem or stud 17 on the bottom of the controlling member 18 is seated inan opening 19 in an elevated step or guide 20 fastened in the bottom ofthe chamber 3 as shown. The member 18 may comprise one or more chambersadapted to contain, for example, ether, alcohol and distilled waterwhich at a certain temperature will cause the member 18 to expand andthereby force the valve 13 against its seat. The valve seat 14 isadjustable by providing the same in the upper extremity thereof with adiametrical notch 21 in conjunction with which the point 10 of the toolmay be used for effecting the desired adjustment of the seat so that thevalve 13 will close at any desired temperature.

Surrounding and inclosing the major portion of the valve cage or chamber12 is a silencer embodying a hollow cylindrical body or shell 22 theupper end of which is normally closed by means of a cap 23 having athreaded connection with the body or' shell'22. The bottom wall of saidshell is formed with a central opening 24 of sulficient size to enablethe silencer to be slid on and od the valve cage 12 and is also lili)llU resting against the bottom wall of the silencer and the top gauzering being held down by the flange of the cap 23 thus conning andholding all of said rings in proper position at all times. These ringsmay be removed and replaced or renewed as requently as found necessary.

The live steam enters the chamber 3 through the pipe 2 and comes indirect contact with .the controller or thermostatic member 18. Thisbecomes heated and effects a closing of the valve 13 against its seatthereby shutting 0E the steam and preventing the same from escaping intothe room. The steam escaping into the silencer is muled by the rings ofbrous material ,thereby making the device noiseless at all shown in Fig.ll. This will cause the times. Water of condensatlon within the chamberAs thel heat subsides, the coolor 3 causes the member 18 to contract,assisted by a coiled expansion spring 28 which encircles the valve stemand is interposed between the member 18 and the cap valve 13 to open andagain admit steam to the 'controlling member located in the condensationchamber and having the valve stem attached thereto, and a vdetachablesilencer inclosing said valve chamber only and comprising a tubularshell, a tubular body of" fibrous packing within said shell, andreticulated packing retaining means adjacent to the opposite ends ofsaid shell, the outer endof said cap being closed and the inner endthereof being formed with vents.

In testimony whereof I aiix my signature in presence of two witnesses.
